Sequential Direction Detection for Sound Scene Analysis
Nail A. Gumerov, Bowen Zhi, Ramani Duraiswami · 2018
We introduce a novel algorithm for the decomposition of a broadband soundfield into its component plane-waves. The algorithm, termed Sequential Direction Detection, decomposes the sound-field into L plane waves by recursively minimizing an objective function that determines the plane-wave directions, strengths and the number of plane-waves. The algorithm is described and tested on synthetic and real data. Extensions are discussed.
